警告
It is very important to note that the line with the closing identifier must contain no other characters, except possibly a semicolon (;). That means especially that the identifier may not be indented, and there may not be any spaces or tabs before or after the semicolon. It s also important to realize that the first character before the closing identifier must be a newline as defined by the local operating system. This is
on UNIX systems, including Mac OS X. The closing delimiter (possibly followed by a semicolon) must also be followed by a newline.
如果这一规则被打破,而封闭式识别器不是“清洗”,则不会被视为封闭式识别器,而购买力平价将继续寻找。 如果在目前档案结束前没有发现适当的封闭标识,则最后线将出现差错。
如果报告错误,那么你所忽略的(在你的文字编辑中强调的空白屏幕和破碎的辛迪加)将是 par误的结果或症状。 很难看出,这是否属于你的职位,不属于实际档案的范围。
检查是否适用。
